“Border Controls work”. I don’t disagree but they aren’t 100%. The Italian patient zero was never in China, and had no contact with anyone from China. Italy’s lack of control didn’t cause his infection. There must be other ways it spreads and that is what wc causing the panic we see.
Also regular flu has killed 10,000 here in the US this flu season, which is just half over (September-May). That includes 54 children, No one is focused on the relative mortality of the two.
Closing borders with few cases and no fatalities seems excessive, as it would cause economic collapse world-wide.
